Beyond the boundaries of established science an avalanche of exotic ideas compete for our attention. Experts tell us that these ideas should not be permitted to take up the time of working scientists, and for the most part they are surely correct. But what about the gems in the rubble pile? By what ground-rules might we bring extraordinary new possibilities to light?

Just a wee bit of humor. If we take all the craniums of all the scientists and fill them with liquidlead, then velcro a north pole in one ear and a south pole in the other ear and then screw a lightbulb in each ear, what do you think we would get.Oh ok, they would still be attached to their bodies.

There is simply no mechanism for accelerating a photon once its velocity has been reduced by a gravitational force! With every gravitational force it encounters, no matter how small, a photon will continue to decelerate and lose energy. I call this “gravity drag”, which was also named by famous astronomer Fritz Zwicky many years ago.

If gravity cannot accelerate a photon, then how does it decelerate a photon?

Acceleration and deceleration are the same thing, they are both a change in velocity.Just opposite vectors of the force which is causing the change in velocity.Isn't it?

Gravity can accelerate a photon. Measuring blue-shift of light being projected down a tower was the basic outline of the Pound-Rebka experiment:
